Illuminati (33rd Degree)

You've got the idea, exactly. The volume in question would be what's behind the cap that's forced through the center pole. I haven't calculated any of the volumes involved because Eminence is working on it. But that's how the problem is caused, when compression exceeds the limits of pneumatic symmetry, which I believe is somewhere around 2 atmospheres. It's probably a little less, perhaps as low as 1.5 atmospheres.
